Abstract
A method for treating sulfur contaminants is provided. The method comprises introducing a methylmorpholine-N-oxide solution to a vessel, wherein the vessel comprises a water layer and a gas layer, wherein the water layer and the gas layer comprise the hydrogen sulfide; introducing methylmorpholine-N-oxide into the water layer; and treating the water layer by allowing the methylmorpholine-N-oxide to react with the hydrogen sulfide.

A method for removing hydrogen sulfide, comprising:
- (A) introducing a methylmorpholine-N-oxide solution to a vessel, wherein the vessel comprises a water layer and a gas layer, wherein the water layer and the gas layer comprise the hydrogen sulfide;
- (B) introducing methylmorpholine-N-oxide into the gas layer;
- wherein the methylmorpholine-N-oxide comprises between about 0.01 weight volume % and about 60 weight volume % methylmorpholine-N-oxide of the gas layer;
- (C) introducing steam to the vessel, wherein steam removes at least a portion of the hydrogen sulfide from the water layer;
- (D) allowing the steam comprising at least a portion of hydrogen sulfide from the water layer to evaporate into the gas layer;
- (E) adjusting a hydrogen sulfide rate of evaporation by increasing the vessel temperature;
- (F) treating the gas layer by allowing the methylmorpholine-N-oxide to react with the hydrogen sulfide;
- and
- (G) treating the water layer by reducing the temperature of the gas layer to a temperature below the boiling point of methylmorpholine-N-oxide to condense into the water layer.
